您好我正在尝试构建一个eclipse hadoop项目，但得到：

遇到同样的麻烦。要构建eclipse hadoop插件，请添加：

reactor.repo=https://repository.cloudera.com/content/repositories/snapshots

到

hadoop_source_pack/src/hadoop-mapreduce1-project/src/contrib/eclipse-plugin/build.properties

一般来说，你需要在build.properties中使用这样的东西：

eclipse.home=/home/cloudera/eclipse
reactor.repo=https://repository.cloudera.com/content/repositories/snapshots
version=2.0.0-cdh4.4.0

这对我有用。我从https://ccp.cloudera.com/display/SUPPORT/CDH4+Downloadable+Tarballs

获得了hadoop分配

Answer 2

您的ivy插件无法解析网址${reactor.repo}/commons-logging/commons-logging/1.1.1/commons-logging-1.1.1.pom

检查变量reactor.repo是否已设置。
